a spouse who is so quick to file for separation and divorce and have you move out of the home doesn't have "positive feelings towards your marriage" as the primary motivator here, I think someone else is involved, I obviously don't have proof and you have haven't been able to find any yourself so it's just an opinion at this point.
Don't leave the home, stand up to her, be strong, confident, cool, calm, collected, don't get dragged into a screaming match, let her argue but let her know plain & clear that you intend to live in your home and that if she really is unhappy with the marriage, filing for separation and you moving out isn't going to make her want the marriage anymore, quite the opposite in fact. She is free to leave and find another place to live, possibly with family and if she needs help, you will help her pack her stuff and move to her new place. You respect her decision to leave the marriage and file for separation but she has to respect the fact that this is your home too and you don't have to leave just because she doesn't want you there. You wished things worked out differently between the two of you but they didn't so you will stop trying to win her back, she is free to do whatever she wants with her life and you will be free to do the same.
Say that, literally.
And that's it, walk away.
If she argues with you, starts screaming, yelling, cursing, saying bad things, you interrupt her and tell her:
"STOP! I HAVE DECIDED that I won't discuss anything with you until you are calm and respectful towards me, I'm done talking right now, when you're ready to be an adult and discuss things rationally, you know where you can find me."
And then walk away, go to another room in the house, and let her be and tell her to NOT follow you, you need a break from her and don't feel like talking right now anymore.
